TRUCK-LOADER.

Specification of Letters Patent.

Patented Sept. 16, 1919.

Application filed September 4, 1918. Serial No. 252,561.

To all whom it may concern:

Be it known that we, Srnvro SABATINI, a subject of the King of Italy, and resident of Milwaukee in the county of Milwaukee and State of Wisconsin, and Cnsann GIOVANELLI, a citizen of the United States, and resident of Weeksburg, Kentucky, have invented new and useful Improvements in Truck-Loaders, of which the following is a description, reference being bad to the accompanying drawings, which are a part of this specification.

The invention relates to loading devices, more particularly adapted for use on automobile trucks.

One of the objects of the invention is to provide a hoist of simple construction which is operated from the drive shaft of the truck.

Another object of the invention is to provide simple means for controlling the operation of the hoist.

Another object of the invention is to provide means for stabilizing the truck when the hoist is in use.

The invention further consists in the features hereinafter set forth and more particularly pointed out in the claim.

In the drawings: Figure l is a side elevation view of the device embodying the invention; Fig. 2 is a plan view thereof; Fig. 3 is a detail view of the hoist-operating mechanism; and Fig. 4 is a section taken on the line 44 of Fig. 3.

In the drawings the numeral 5 designates the truck body, 6 the drivers cab, 8 the loading platform, 9 a fitting secured to the latform 8, 10 a mast or upright revo ubly mounted at its lower end in said fitting and at its upper end in a bracket 11 secured to the top of the cab 6, 12 and 13 brackets secured to the upright 10, and 14 a handle for turning said upright about its pivotal sup ort. p The bracket 12 has a boom 15 vertically pivotally secured thereto, and the bracket 13 has a guide pulley 16 vertically pivotally secured thereto. The boom is adapted to be manually raised and lowered by means of a rope or cable 17 which is fastened at one end to the housing 18 for the pulley 16, and thence passes around a pulley 19 secured to a bracket 20 on the outer end of the boom and thence passes back over the pulley 16 and is secured at its other end to a holding cleat 21 on the upright 10.

With this construction, the boom may be raised and lowered in a vertical plane or swung about its support.

The hoisting means consists of a drum 22 mounted on a shaft 28 and carrying a cable 24 which passes upward through a guide pulley 25 on the bracket 12, and a guide pulley 26 secured to the bracket 20, .and carries a suitable load attaching member such as a hook 27.

The hoist is driven by power to raise the load from a driving connection with the engine shaft 28 of the vehicle which consists of the usual toothed clutch 29, and a gear train consisting of a spur gear 30 on the shaft 28 meshing with a gear 31 on a shaft 32, carrying a gear 33 meshing with a gear 34 on a shaft 35, which carries a worm 36 meshing with a worm wheel 37 on the shaft 23. This gear train provides for a reduction in speed for the drum drive. The movable member of the clutch 29 is thrown into and out of driving relation with gear 30 loosely mounted on the shaft 28 by means of a bell crank lever 38, connecting rod 39, and shifting lever 40 provided with the usual means for locking the lever such as a spring pressed pawl and locking plate.

The drum 22 is loosely mounted on the shaft 28 and is adapted to be secured thereto for winding up the cable to raise the load by means of the usual toothed clutch 41, the movable member of which is slidably but non-rotatatably mounted on the shaft 23, and is shifted into and out of engagement with the other clutch member by means of a shifting lever 42 which is adapted to be locked in adjusted position by the usual locking means such as a spring pressed pawl and locking plate. The lowering of the load is accomplished by unwindin the cable from the drum due to the weig t of the load and a band brake 43 surrounding a brake wheel 44 on the drum and controlled by a lever 45 also having suitable means for locking it in different positions.

In order that the hoist may be 0 erated from the main drive shaft 28 of t e machine, this shaft is adapted to be connected or disconnected from the drive shaft 46 to the rear wheel through a well known form of toothed clutch 47 controlled by a lever 48 through a lever 49 and rod 50.

To prevent tipping of the truck, and to brace the hoist when heavy loads are lifted, we provide a box shaped channel bar 51 extending transversely of the truck body and disposed beneath the truck platform adjacent the loading device and having bars 52 slidabl y mounted therein to which lifting jacks 53 are vertically ivotally secured so that they may be turned down to rest upon the round and which may be held u out of t eway when not in use by hoolis or catches 54.

In the use of the device the jacks 53 are released from the catches 54, the bars 52 drawn out and the jacks let down and tight ened up. The real-shaft 46 is disconnected from the main shaft by throwing out the clutch 47. Then with the boom in the desired elevated position and swung out over the truck with the cable attached to the load to be lifted, the clutches Q9 and 4-1 are thrown in to cause the drum to wind up the cable and raise the load. The clutches 29 and 41 are then thrown out, the brake 43 applied, and the boom swung to bring the load over the truck, and the load is lowered by releasing the brake 43.

What we claim as our invention is:

In combination with an automobile truck havinrz; rear driving wheels, a load supporting p atform, and truck driving means conheating the engine and the rear driving wheels, a loading device COlnPllSiIlg a derrick mounted on the truck, a drum mounted below said loading platform and having a cable connection with said derrick, a drum driving mechanism also mounted below said lead supporting platform and including a shaft upon which said drum is loosely mounted, a clutch mechanism for connecting and disconnecting said drum driving mechanism to and from said truck driving means, another clutch mechanism for conmeeting and disconnecting said drum from the drum supporting shaft, a third clutch mechanism for connecting and disconnecting the truck clriving means from the drivin wheels, said third clutch being positione between said drum and its driving mecha nism and said driving wheels.

In testimony whereof, We aiiix our signatures.
